“…This problem, also known as the "cosmological constant problem" because of its obvious connection with the introduction of a cosmological constant in Einstein gravitation equations [17,18], has remained unsolved during the twentieth century, despite considerable efforts for proposing solutions [19][20][21]. It has the status of a paradox, lying just at the crucial interface between quantum theory and gravity, and pointing at the necessity of substantial reformulations in the present theoretical formalism.…”

The existence of irreducible field fluctuations in vacuum is an important prediction of quantum theory. These fluctuations have many observable consequences, like the Casimir effect which is now measured with good accuracy and agreement with theory, provided that the latter accounts for differences between real experiments and the ideal situation considered by Casimir. But the vacuum energy density calculated by adding field mode energies is much larger than the density observed around us through gravitational phenomena. This ``vacuum catastrophe'' is one of the unsolved problems at the interface between quantum theory on one hand, inertial and gravitational phenomena on the other hand. It is however possible to put properly formulated questions in the vicinity of this paradox. These questions are directly connected to observable effects bearing upon the principle of relativity of motion in quantum vacuum.Comment: 8 pages, 2 figures, contribution to a special issue in CRAS (Comptes rendus de l'Academie des Sciences), corrected typos, added reference

“…In contrast the Cosmic Background Energy has been suspected to exist for well over a century. From theoretical considerations of Newtonian gravitation, the Cosmic Background was surmised by Seliger in 1895 (Demianski [17]). Einstein first included the Cosmological Constant in the GR field equations, then rescinded it, and later accepted the idea (Carroll and Press [18]).…”

The premise is that two energy fields influence all motion in classical physics. The first is the omnipresent Cosmic Background, the existence of which has been suspected for over a century, but with significant disagreement on the intensity. The second is the Mass Energy Field (ME) hypothesis on the existence of a localised energy field around every particle with mass and/or momentum. The spatial integral of the ME field for every massed particle is given by Einstein’s Mass Energy Equivalence Principle. The ME model leads to startling simplifications of several problems of significance of the past century that were considered almost intractable and required genius innovations: Einstein’s General Relativity (in the Solar System), 1916; Dirac Wave Function, 1928; and the Lamb Shift, 1947. The ME solutions, based on classical physics and conforming to Special Relativity, are simple, compact and do not require spacetime curvature, vacuum fluctuations, or renormalisation. For micro particles the ME model indicates a possible analytic expression for the Casimir Force, Lamb Shift, and the Strong Nuclear Force. The ME field around a massed particle, and the similar momentum energy field around a photon provide a plausible explanation for the century old vexing conundrum of wave-particle duality and points to a possible communication mechanism between quantum entangled particles. The Muon g-factor, computed with the ME expression, very different from existing QED theory, agrees with the measured value to 12 parts per billion. The ME theory shows exact agreement with General Relativity effects within the Solar System.
